Project Title: Assessment of Environmental Performance of an Electric Bus


TUMCREATE is a research platform for the improvement of Singapore's public transportation, including the deployment of electric and autonomous mobility. Researchers from Technical University Munich and Nanyang Technological University join forces and are funded by Singapore’s National Research Foundation as part of the Campus for Research Excellence and Technological Enterprise (CREATE).

In TUMCREATE, over 100 scientists, researchers and engineers work together, led by Professors from the Technical University of Munich and Nanyang Technological University. The Mission of TUMCREATE is to seek the ultimate public transport system for the people of Singapore. Our innovative road transport solutions will provide high comfort and a positive travel experience, best protection of the environment and maximum benefit to the society and the economy.

About this Position

The research group Electrification Suite & Test Lab (ESTL) in TUMCREATE puts an emphasis on the interaction of the electricity grid with advanced electrified public transport systems for Singapore. Ranging from charging infrastructure optimisation to demand side management and integration of renewable energies, environmental benefits of transport electrification, ESTL covers many hierarchy levels of the electrification concept in the context of the major goals of TUMCREATE.

A research project has been established evaluate the environmental performance of electric buses in Singapore. About 20 % of greenhouse gases and 39 % of NOx emissions arising from road transport in Singapore comes from its diesel buses. Electrification of buses shall help reduce the emission arising from road traffic. However, electric buses produce indirect emissions at the power plants. Hence to be able to quantify the emission saving potential of an electric bus, a well to wheel analysis is required. The driving behaviour and environmental conditions has a great influence on the vehicle’s energy consumption. Thus, it becomes necessary to calculate the energy needs of electric buses specific to Singapore’s conditions.

The goal of this master thesis / internship is to evaluate the environmental performance of an electric bus in Singapore.

The main tasks are:

  1. Evaluation of the emissions of electricity and diesel production in Singapore,

  2. Estimation of the emissions of diesel and electric bus manufacturing,

  3. Calculation of the energy demands of a diesel and electric bus (specific to Singapore) based on the driving pattern and environmental conditions,

  4. Comparison of the environmental performance of a diesel and electric bus on a ‘per km driven’ basis.

The model developed should be completely parameterised to enable changes and scaling in future.


  • Good knowledge of vehicle energy needs estimation.

  • In-depth knowledge in Life Cycle Assessment techniques and well to wheel analysis.

  • Knowledge of ecoinvent and SimaPro is preferred.

  • Excellent interpersonal skills and communication skills in both written and spoken English and ability to work with people from different backgrounds and cultures
